Just use a DNS SRV record instead.

A proxy that not only let you run multiple virtual Minecraft servers but can also handle different protocols all of which on one port. Current supported protocols:

• Minecraft
• IRC (unencrypted)
• HTTP
• HTTPS*

*note: without client authentication works, I haven't tested the other ones.

You will also need to add the correct certificates.

• Some internet providers block certain ports.
• Corporations/organisations have a firewall, running everything on 80 or 443 might fix this.
• ...

there are ony 2 commands:

• reload - this will reload the configuration file.
• quit - exit the program.

When you run the program for the first time a config wil be generated in the same directory. You can also start with the config as a parameter. Example:

MultiProxy.exe C:\someDir\aConfigFile.xml

<?xml version="1.0" encoding="utf-8" ?>
<multiproxyserver>
  <port>1212</port>
  <endpoint>0.0.0.0</endpoint>
  <motd>A Minecraft Proxy</motd>
  <pingremote>true</pingremote>
  <usersinmotd>true</usersinmotd>
  <vhosts>
	<vhost host="example.com" destination="localhost:25565" />
	<vhost host="test.example.com" destination="localhost:25569" />
	<vhost host="alpha.example.com" destination="localhost" />
	<default destination="localhost:25565"></default>
  </vhosts>
  <webserver>qyour-site.tld:80</webserver>
  <ircserver>irc.kreynet.org:6667</ircserver>
</multiproxyserver>

port: The proxyserver wil be listening on this port. Defaults to 25565

motd: The message of the day is the same for each server. Defaults to "A Minecraft Proxy".

pingremote: If enabled the playercount and max player will be the sum of vhosts. Defaults to false.

usersinmotd: If enabled the motd will be appended with a list of all servers and the amount of players, example: "A Minecraft Proxy Servername (3/20) ServernameTwo (1/20)".

vhosts: A list of virtual servers.

vhost: A virtual server, host is the address that a client connects to, destination is where the server actualy runs. The port number is optional.

webserver: The webserver to where all requests are forwarded. You don't need to add virtual hosts here, the webserver should handle that.

Defaults to "localhost", the port defaults to 80.

When a browsers connects using HTTPS then the proxy will allways use 443.

ircserver: The IRC server. Defaults to "localhost", the port defaults to 6667.
